Amafutha Hydrogenated: uhlu izici

Engxenyeni zenzeka ekhulwini lamashumi amabili endaweni yokudla yesibili ziye kabanzi amafutha hydrogenated. Ayebhe- alternative ewusizo ezilwane. Kodwa eminyakeni yamuva ososayensi bathole ukuthi le ndlela yokwelapha iguqula zemifino amafutha ewusizo e kabi siyagwinyeka amafutha okuqinile. Nokho, kuze kube manje iningi imikhiqizo ngokuphakeme ezimbonini ekhiqizwa aqukethe hydrogenated amafutha, ngoba babebadala ishibhile kuka zemvelo.

Yini lena

Ezilwane okuqinile emazingeni okushisa okuvamile. Ukuvumelana efanayo kanye nemikhiqizo esekelwe phezu kwalo. Uma emzimbeni, baqala ancibilike. Zemifino amafutha kukhona uketshezi ngaphansi kwezimo ezivamile, akusiyo sihlale siwusizo ngendlela yezomnotho. Ngakho-ke, basuke Ushintshe ziphenduka amafutha okuqinile. Healthy unsaturated okunamafutha acid e zemifino amafutha eziguqulelwa ayegcwele.

Lokhu kwenzeka ngokubeka amalahle ukuphathwa hydrogen umfutho ophakeme. Umphumela eyatholakala kusukela amafutha yemifino noma imajarini okuthiwa amafutha Trans. Okunjalo trans fatty acid akhiwa lapho i-molecule ye-hydrogen senzeka engqamuzaneni amafutha. It kuvela mafutha ukuzinza yanda, okuyinto has a ukuphila eshalofini eside. Kodwa umzimba angakwazi ukuqonda okunjalo ephezulu ukuncibilika amafutha.

Ngo umkhakha, esikhundleni ezivamile ngokuvamile esetshenzisiwe hydrogenated amafutha zemifino. Phela, kuba ishibhile futhi isikhathi eside akusho ukuwohloka. Ngakho imikhiqizo okusekelwe kuso zingagcinwa isikhathi eside. Ngaphezu kwalokho, lezi amafutha njalo wasebenzisa ukuthosa ukudla zokudla okusheshayo izindawo ukudla. Phela, nabo basuke emsini kancane, ngakho amafutha ngalinye ekukhonzeni, ungakwazi Fry ukudla okwengeziwe.

Indaba

Eminyakeni engaphezu kwengu-100 edlule, usokhemisi French Inter-Mourier wadala imajarini. Ubelokhu wajuba ukukhiqiza ezishibhile futhi amelana umonakalo esikhundleni ibhotela. Kufanele ziye zasetshenziswa phakathi kwabantu abampofu ngoxhaxha. Inter-Mourier kwaba ibhotela esikhundleni by ukwelashwa nge sezinkomo amakhemikhali amafutha uphehle ngayo ubisi. Umkhiqizo kwaphumela wawubizwa ngokuthi "imajarini".

Eminyakeni embalwa kamuva omunye usosayensi French uPawulu Sabatier ngasekupheleni XIX leminyaka wavulwa hydrogenation indlela. Kodwa kuphela ekuqaleni kwekhulu lamashumi amabili ke yomthetho ukwenziwa amafutha okuqinile kusuka amafutha liquid.

Inkampane yokuqala ukuthi baqala ukunyathelisa amafutha hydrogenated, kwaba Procter & Gamble. Ngo-1909 waqala ukwenza imajarini esekelwe uwoyela lamakinati.

Aqukethe amafutha hydrogenated

Lezi amafutha avame ukusetshenziswa ukwenziwa ezahlukene imikhiqizo ukudla esiphelele. Bayakukhanda amazambane chips, corn ishq, imikhiqizo Semi-siphelile. Ungathola nabo amakhukhi nama-crackers, donuts namaswidi. Nososo, isoso kanye imayonnaise ngokuvamile aqukethe lezi amafutha, lapho betholakala khona ngisho kwezinye imikhiqizo yobisi iphalishi ngomumo eyenziwe. Zonke ukudla okusheshayo uzilungiselele nge iqhaza zabo: fries French, amabhega, inkukhu okuyigugu.

ibhotela elithambile kakhulu eyatholakala lapho yayo elihlale okunamafutha acid ne-hydrogen baguquka emafutheni Trans. Abathengi bakholelwa ukuthi ukudla amafutha enempilo, kodwa empeleni uthola yingozi impilo amafutha hydrogenated. Kuphela eminyakeni yamuva on the isembozo nge umkhiqizo waqala ukuloba ukuthi "zisakaze 'Esikhundleni samafutha. Ukuthandwa lo mkhiqizo kungenxa izindleko zalo ongaphakeme kanye nenani elikhulu isithokela izithasiselo kwenza kube esihlwabusayo.

Umonakalo kwamafutha ezifana

Naphezu imvelaphi yemifino, amafutha hydrogenated eyingozi empilweni. Imikhiqizo equkethe kubo, zikhangiswa njengoba ukudla okunempilo, ngoba ziyisisekelo unsaturated yemifino amafutha. Kodwa ziba te nemithi hydrogen. ososayensi ucwaningo lwamuva luye lwabonisa ukuthi njalo ukudla esiningi amafutha emzimbeni izinguquko olunje:

• kwandisa umthamo cholesterol;
• It kwandisa ingozi yesifo senhliziyo,
• kahle fat umzimba;
• siba sibi umsebenzi ingqondo;
• testosterone okhathazekile;
• eziwohlokayo izinga ubisi lwebele;
• It kwandisa nengozi yokukhuluphala nesifo sikashukela,
• ebucayini sokuzivikela ezifweni;
• It kunciphisa inani prostaglandins;
• ukuthuthukisa komzimba.

Ukusebenzisa e Cosmetology

Trans fatty acid ziyasatshalalaiswa embonini yezokudla futhi Cosmetology. Banezinhliziyo ongaphakeme ukuma, bengazange spoilt futhi ube ukungaguquguquki obukhulu. Lokhu kwenza lezi amafutha athandwa kakhulu Cosmetology. Ezisetshenziswa kakhulu uwoyela ocolisekileyo hydrogenated. PEG izidakamizwa 40 ivuliwe kwesisekelo salo, esiwulwazi isetshenziswa njengenhlangano emulsifier kanye kuphela. Ngenxa izakhiwo zalo amafutha abalulekile kanye amafutha zitholakala kalula encibilikayo abezindaba aqueous.

La mafutha esihlahla lalisetshenziswa tonics kanye lotions, ubisi yezimonyo, iziqeda-usawoti Scrubs, amashampu futhi isimo, umzimba spray kanye notshwala antiperspirants khulula.

Hydrogenated ocolisekileyo kancane ine Izakhiwo ezilandelayo:

• It ithambisa isikhumba;
• sivuselela ibhalansi amanzi;
• It lihlanza ukungcola;
• Akukona baxabane nomzimba.

amafutha sunflower Ikakhulukazi

Lona amafutha ezivamile asetshenziswe iminyaka eminingi ngenxa yokudla komuntu. uwoyela Sunflower - siwumthombo omuhle kakhulu unsaturated okunamafutha acid, ngakho-ke kuhle empilweni. Kodwa eminyakeni yamuva nje iye ngokuya abe nendlela yakhe akhethekile okusingatha amacala, ukwandisa impilo eshalofini kanye nezindleko. La mafutha esihlahla elicwengiweyo is naye touted njengoba ewusizo kakhulu. Kodwa is etholwe ahwamukayo futhi compounds ngamakhemikhali akhethekile. Ngenxa yalokho, kukhona semali amafutha Trans.

Uma kuhlangene Ukushisa ne-hydrogen, hydrogenated amafutha sunflower eyatholakala. Kunzima, refractory, nalapho ukuthosa ungahambi Rancid futhi ehlaza. Lokhu amanoni bayindlala kakhulu kule iIgama nokudla izimboni.

uwoyela soybean

Kusukela ekuqaleni kwekhulu lamashumi amabili, abantu baye baba kabanzi kudliwa lwamafutha imbewu sayinela ukungena. Kuyinto ecebile unsaturated okunamafutha acid futhi izuzisa kakhulu empilweni. uwoyela soybean kugaywe kalula, futhi normalizes lomgudu wokugaya ukudla bese kuqinisa amasosha omzimba. Kodwa semali linolenic acid ngezinye izikhathi ulunika ukunambitheka kabi engazinzile lapho sishiswa ngakho. Ngakho-ke, kusukela phakathi kwekhulu lamashumi amabili, baqala ukusebenzisa hydrogenated uwoyela soybean.

Kule nqubo ehluleka ukufeza kuncishiswe inani linolenic acid. Khona-ke ngo-okokuqandisa amafutha isuswe amafraktjhini okuqinile. It kuvela amafutha isaladi emangalisayo, okuyinto ethandwa kakhulu emhlabeni wonke. Futhi ngenxa yokuthi imikhiqizo yayo ukwenza imajarini, lisakazeka futhi ukupheka amafutha, njengoba bebizwa ukuthosa ungayishisi futhi ungenayo i nephunga edabukisayo.

uwoyela ukudlwengula

Lokhu amafutha is kabanzi embonini zamakhemikhali. uwoyela rapeseed isetshenziselwa ukukhiqizwa Izingxube kuqhume, antifreezes, e ukucutshungulwa iphepha kanye lesikhumba. Kodwa muva nje liye isicelo endaweni yokudla, ikakhulukazi ngokuvamile - ukwenziwa confectionery iziphuzo ezidakayo. Ngenxa yale njongo, hydrogenated uwoyela rapeseed. It is njengoba ukudla okufakiwe E 441 ezaziwayo.

Ngu ukwelashwa nge-hydrogen ukususa kusuka uwoyela rapeseed okungenamsoco erucic acid ukususa intukuthelo. It yayisetshenziswa njengesikhungo isimame futhi emulsifier. La mafutha esihlahla isiza ukugcina ukungaguquguquki kanye ukuma ukudla, uhlanganise yezingxenye. Ngokuvamile, lokhu mkhiqizo isetshenziswa Cosmetology njengoba ukuthambisa isikhumba igcina ukulinganisela kwaso amanzi.

Kodwa naphezu kweqiniso lokuthi Khangisa hydrogenated uwoyela rapeseed njengoba ewusizo, iletha umonakalo omkhulu empilweni. Iqukethe amafutha trans, eziphula umzimba, ukwehlisa ukungatheleleki kwandisa ingozi yokungenwa izifo zenhliziyo nemithambo yegazi kanye nokukhuluphala ngokweqile.

amafutha esundu

Kusukela ekupheleni kwekhulu lamashumi amabili kuwo wonke amazwe iye kabanzi lwamafutha izithelo wamaSundu. It usuthandwa ngenxa eziphansi kanye ukuphila eshalofini eside. Yemvelo amafutha esundu iqukethe unsaturated igcwaliswe-fatty acid, amavithamini, amaphrotheni. Naphezu kwakho konke lokhu, lokho kubhekwa njengokuzijabulisa hhayi usizo kakhulu. Nakuba sahlazo hydrogenated amafutha esundu. Okungukuthi, ke esanda kabanzi embonini ukudla, ikakhulukazi ekukhiqizeni imikhiqizo yobisi, confectionery baby ukudla.

Ungacabangi ukuthi uma isembozo umkhiqizo uthi ukwakheka kuhlanganisa "amafutha yemifino", kuyasiza ngempela. amafutha Ngokuvamile hydrogenated kunezelwa ngisho nebhotela. Ngakho-ke, kumelwe sibheke intengo umkhiqizo futhi eshalofini yokuphila yalo.
